Page rendering is not happening in proper order

Hi All,
I have an issue in rendering a jsp page in another jsp page for IE8 browser.

I am using tiles insert tag[ ] to include the child jsp page in the parent page. The parent page holds a header with a heading text, the tile insert tag for child jsp page, two images in a div and the footer below to the inserted page.

Usually the child jsp page will contain a big chunk of data and take some time to render in the browser. In IE7, the bottom placed images will be shown only when the child page is fully rendered, but in IE8 it is not happening. Instead, the parent page is rendered fully before the child jsp page is getting fully rendered in browser.

Could somebody know why this strange behaviour is happening in IE8 browser.
